Although many Pseudomonas syringae strains have already been determined, only a few genomes of strains belonging to pathovar lachrymans have been sequenced so far. In this study we report the genome sequence of P. syringae pv. lachrymans strain 814/98, which is highly virulent to cucumber. The genome size was estimated to be 6.58 Mb, with 57.97% GC content. In total, 6024 genes encoding proteins and 92 genes encoding RNAs were identified in this genome. Comparisons with the available sequenced genomes of pathovar lachrymans as well as with other P. syringae pathovars were conducted, revealing the presence of three unique plasmids and 24 type III effector proteins (TTEs) in strain 814/98. The phylogenetic analyses of MLST loci and TTEs clearly showed the existence of two distinct clusters of strains within pathovar lachrymans, which were grouped into either phylogroup 1 or 3, supporting non-monophyly within this pathovar.
